Novel solid $$^4$$He targets for experimental studies on nuclear reactions: $$^6$$Li + $$^4$$He differential cross-section measurement at incident energy of 5.5 MeV

A specially prepared Si/He thin solid film was investigated as a suitable target for experimental studies on nuclear reactions involving He targets. For that purpose, the elastically scattered He recoil coming from the reaction Li + He at incident energy of 5.5 MeV was measured. The differential cross section of Li on He has been found to be fully consistent with previous measurements in the literature. The prospective advantages of using these solid He targets in experiments at radioactive beam facilities are discussed.
